I agree on most of the part of the original post.
however, You didn't consider engine braking into the account. If the car is outputing higher torque, engine break will drag the car a lot more (I am saying right after shooting the flame doing 140mph on the highway in 5th gear and downshift while braking ). engine break will cause the more load on brake and tires if you have higher torque. Well, if you popp the gear to neutral then break,then it doesnt matter.
So I would say if your car is creating a lot more power, then better brake actually helps ( of course besides the good tire) in many cases.
